49-494 25mm Dia. x 100mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-494 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This lens boasts a 25mm diameter and a focal length of 100mm, making it suitable for a wide range of applications.
The lens is constructed from N-BK7 Schott glass, a popular material due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 103mm and -103mm for the first and second surfaces, respectively. This geometry results in a high refractive power, making the lens ideal for focusing or collimating light.
The lens has a thickness of 2.48mm at the edge and 4mm at the center. The effective focal length (EFL) is 100mm, and the back focal length (BFL) is 98.95mm. The lens does not have any inner or outer radius, indicating a uniform thickness across the lens.
The 49-494 lens is coated with Edmund Optics' NIR I standard curve coating on both the front and back surfaces. This coating is specifically designed for use in the near-infrared region, between 600nm and 1050nm, enhancing the lens's performance in this spectral range.
